外耳道胆脂瘤30例临床分析（英文）

目的：探讨外耳道胆脂瘤的临床特征和最佳治疗方法,提高临床诊治水平。方法：回顾性分析30例（32耳）外耳道胆脂瘤患者的临床资料。12耳病变局限于外耳道无明显骨质破坏,经耳内窥镜下行胆脂瘤清除病术;10耳病变局限于外耳道,但有较广泛的骨质破坏或有外耳道口狭窄者,经耳内切口显微镜下清除病变并加行外耳道成形术;10耳病变侵及鼓室或乳突,在显微镜下经耳后切口行乳突根治术。有条件者行乳突根治术加鼓室成形术。结果：本组病例所有患者术后病理均为胆脂瘤。术后外耳道口保持宽大,外耳道皮肤恢复正常,不产生上皮堆积。随访1年以上胆脂瘤无复发。结论：耳内镜与显微镜配合应用可彻底清除胆脂瘤,防止胆脂瘤残留和复发,并能提高听力.

Analysis of 30 Cases with External Auditory Canal Cholesteatoma

Objective：To investigate the clinical features and the optimal treatment to improve clinical diagnosis and prognosis of external auditory canal cholesteatoma（EACC）.Methods：A retrospective study was carried out 30 cases（32ears） with EACC were chosen.12 ears whose lesion located in external auditory canal without bone destruction were cleared the lesion under ear endoscope;10 ears whose lesion located in external auditory canal with extensive bone destruction or stenosis were cleared the cholesteatoma and doneexternal auditory canal plasty by endaural incision under microscope;10 ears whose lesion invaded into tympanic cavity or mastoid weredone radical mastoidectomy by postauricular incision,if it＇s fitting,typanoplasty was done in addition.Results：All the patients were diag-nosed EACC in pathology.After surgery,the external auditory canal generous was kept,and the skin returned to normal to prevent epithelium accumulating.They had no reoccurrence in more than one year＇s following up.Conclusions：The combination of endoscope and microscope could remove cholesteatoma completely which will prevent residue and recurrence and improve hearing.
